Phœnix Parc Floral de Nice is the world’s largest greenhouse. Seven different tropical climates (damp, in other words) covering seven hectares, packed with 2,500 different plants. You can walk in the shadow of an (almost) unknown palm tree here, look at a baby shark, smell a thousand flowers and listen to bird song- on the loudspeakers.

In the days of the tsars, the people who enjoyed themselves in the Riviera’s casinos until late on Saturday night, were not exactly short of money. They went here, to church though, on Sundays. After the collapse of communism in Eastern Europe, things are much as they were in the old days, but thick wads of dollars now rain down on the Riviera — and the beautifully restored cathedral. Strict dress code applies.

One of the oldest and largest mosques in China, the Great Mosque of Xi'an is a fascinating blend of Islamic and Chinese architectural styles. Built in the 8th century, it’s a stunning example of how different cultures can come together in harmony. As you wander through its peaceful courtyards, you’ll spot pagoda-like minarets, intricately carved wooden beams, and beautiful Arabic calligraphy—all set against a backdrop of serene gardens. The mosque is still an active place of worship, offering visitors a chance to witness the unique fusion of Chinese and Islamic traditions.
